Specification of Letters Patent.

Application filed February l1, 1905. Serial No. 245,259.

T0 all whom t may concern:

Be it known that I, PERRY S. BAUER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Sanitary Napkins, of which thefollowing is a specification.

The object of this invention is to render a sanitary napkin waterproofat its back to prevent the excretions soaking through and also to holdthe pad in its proper place as a part of the napkin.

The invention comprises the napkin as a new article of manufacture andalso the novel method of making it.

I have illustrated one embodiment of the invention in the accompanyingdrawings, in which- Figure l shows the pad on the sheet of fabric whichforms the holder and the adhesive strip (indicated by broken lines) inits proper position on the pad. Fig. 2 is a plan View of the napkin.Fig. 3 is an elevation. Fig. 4 is an exaggerated detail sectional viewshowing the manner in which the adhesive becomes incorporated with thefabric.

In its preferred form the napkin comprises a pad 5, of absorbent cotton,inclosed within a fabric holder 6, which is sealed to retain the pad inplace therein. The holder is preferably made of gauze and of suitablesize to envelop the pad and extend beyond the ends thereof. Between oneside, otherwise the back, of the pad and the holder I provide waterproofmaterial, preferably a strip 7 of gutta-percha tissue, which extendslengthwise of the pad and beyond the ends thereof and is incorporatedwith the pad and holder by heat and pressure.

In the manufacture of the napkin I proceed as follows: A pad of suitablesize is placed upon a sheet of gauze and the adhesive strip laid on thepad, as shown in Fig. 1, the adhesive strip being indicated by brokenlines. Then the gauze sheet is folded upon the pad and adhesive, withone side edge, as 8, lapped over the other edge 9 sufficiently toenvelop the pad, as shown in Fig. 2. The adhesive strip lies upon thepad and beneath the lapped edges of the gauze and extends beyond theends of the pad, being indicated clearly by the dark part in Fig. 2.Then heat and pressure are applied to incorporate the adhesive with thepad and gauze to secure the pad against endwise displacement in theholder. This can be done by passing a hot iron lengthwise over theholder, when a long strip of adhesive is used, to incorporate theadhesive with the pad and with the gauze at the back of the pad andbeyond both ends thereof, or the iron may be passed across the holder atthe ends of the pad and over the adhesive there inclosed by the holder,in which case the adhesive will be incorporated with the gauze to sealthe holder at the ends of the pad, and this will hold the pad in placein the holder. For this purpose the adhesive may be provided only at theends of the pad; but I prefer to employ the gutta-percha tissue or someequivalent material at the back of the pad, whether or not it beincorporated with the pad and holder, to make the pad moistureproof atits back, as well as to employ said tissue at the ends of the pad toseal the holder. If the adhesive strip terminates at the ends of thepad, it will, when incorporated, as described, with the pad and holder,securely hold the pad in the holder; but I prefer to seal the holder atthe ends of the pad, because the ends of the holder are thereby bet.-ter maintained in their folded-Hat condition.

When the heat and pressure are applied, the tissue melts sufficiently topermeate to a more or less extent through the interstices of the gauze,as I have endeavored to indicate in Fig. 4; but it is only necessarythat the tissue should act as a binder to stick the layers of gauzetogether. If it is not desired to make the pad moisture-proof at theback, a narrow strip of adhesive may be used to unite the folded sideedges of the gauze together and to the pad. I prefer to use gutta-perchatissue as the binder and moisture-proof material; but equivalentmaterial may be employed, if preferred.

Without limiting myself to the exact construction and arrangement ofparts herein shown and described, what I claim, and desire to secure byLetters Patent, is-

1. A sanitary napkin comprising an absorbent pad, a fabric holderinclosing said pad and sealed at the ends of the pad, and a strip ofmoisture-proof material interposed between one side of the pad and theholder to render the pad impervious to moisture at that side.

2. A sanitary napkin comprising an absorbent pad, a fabric holderinclosing said pad, and a strip of adhesive material interposed be;

IOO

tween one side of the pad and the holder and incorporated therewith torender the pad impervious to moisture at that side.

3. A sanitary napkin comprising an absorbent pad, a fabric holderinclosing said pad, and adhesive material interposed between one side ofthe pad and the holder and incorporated with the holder to seal theholder at the ends of the pad and render the pad impervious to moistureat that side.

4. A sanitary napkin comprising an absorbent pad, a fabric holderinclosing the pad, and adhesive material interposed between one side ofthe pad and the holder and extending bevond the ends of the pad andincorporated with the pad and the holder to render the pad impervious tomoisture at that side.

5. A sanitary napkin comprising an absorbent pad, a fabric holderinclosing the pad1 and a strip of gutta-percha tissue interposedbebetween one side of the pad and the inclosing fabric to render the padimpervious to moisture at that side and incorporated b v heat andpressure with the pad and the fabric to fasten together the overlappingedges of the fabric upon the pad. v
